PYFCHP 3x3

PYROELECTRIC SENSOR D
DIE
Introduction
Pyreos is pleased to present our unique
thin film pyroelectric 3 x 3 element array
detector as bare die. This die is optimized
for maximum performance in the 3
3-5
micron range. The 3x3 array can be
incorporated into standard TO packages
and provide exceptional performance at
low cost. Please contact Pyreos if you
require optimized performance outside this
spectral range.

Packaging Information:
The sensor die have good thermal and mechanical stability and are compatible with standard
semi-conductor back-end processes:
end
•
Epoxy die attach process
•
Gold thermo sonic ball bonding
•
Ultrasonic wedge wire bonding
•
Automated pick & place equipment
For the purposes of die attach Pyreos recommends that
•
Thermally conductive epoxy is used
•
Only three sides of the die are attached with epoxy. An air gap should be present under
the fourth side to ensure that no pressure differential builds up across the membrane.
•
No mechanical contact should be made with the membrane surface. The membrane
must remain stress and damage free during die attach and wire bonding processes.
